Moore surname: questions
Is Moore an Irish or an English surname?
It can be either. Woulfe gives Moore as an anglicised form of the Gaelic Ó Mórdha (O'More of Leix), and also of de Móra, from Norman 'de la More' and Middle English 'atte Mor', an old Anglo-Norman surname in Ireland; he says their anglicised forms cannot be distinguished. Other Moores came later: Webb says the Viscounts Drogheda descend from Sir Edward Moore, a soldier of fortune who 'came over in Elizabeth's reign'.[1][2][5]
What does the surname Moore mean?
For Ó Mórdha, Woulfe gives 'descendant of Mórdha' (majestic). For de Móra he gives 'at the moor or heath, from residence thereby'.[1][2]
Are Moore and O'More the same name?
Sometimes. Woulfe lists O'More, O'Moore, More and Moore among the anglicised forms of Ó Mórdha, the chiefs of Leix. But Moore is also a form of the Anglo-Norman de Móra.[1][2]
Where in Ireland is the Moore name found?
The O'Mores were chiefs of Leix, and the remnant of the clan was moved to Kerry in 1609. In the 1890 Births Index every county had Moores, principally Antrim, Dublin, Londonderry, Cork, Kildare and Tyrone.[1][8]
How common is Moore in Ireland?
In Matheson's 1890 survey Moore was 20th of the hundred principal surnames, with an estimated 17,700 people.[7]
